Bluetooth: Add delayed init sequence support for UART controllers
This patch makes it possible to have UART drivers perform an internal initialization before calling hci_register_dev. This allows moving a lot of init code from user space (hciattach) to the kernel side, thereby creating a more controlled/robust initialization process.
